NAME

       io_uring_prep_ftruncate - prepare an ftruncate request

SYNOPSIS

       #include <liburing.h>

       void io_uring_prep_ftruncate(struct io_uring_sqe *sqe,
                                    int fd,
                                    loff_t len);

DESCRIPTION

       The  io_uring_prep_ftruncate(3) function prepares an ftruncate request. The submission queue entry sqe is
       setup to use the file descriptor fd that should  get  truncated  to  the  length  indicated  by  the  len
       argument.

RETURN VALUE

       None

ERRORS

       The  CQE  res  field  will  contain  the result of the operation. See the related man page for details on
       possible values. Note that where synchronous system calls will return -1 on failure and set errno to  the
       actual  error value, io_uring never uses errno.  Instead it returns the negated errno directly in the CQE
       res field.
